What is Phosphatidylserine?
Phosphatidylserine is a class of phospholipids that serves as a fundamental building block for cell membranes. Unlike cholesterol, which provides rigidity, PS 100 phosphatidylserine allows for membrane fluidity and flexibility. It is most highly concentrated in neural tissues-specifically the brain-where it facilitates neurotransmitter release, synaptic function, and cellular signaling.
The body can synthesize phosphatidylserine endogenously; however, this synthesis often becomes inefficient with age, stress, and poor nutrition. Consequently, exogenous sources-either through diet or supplementation-become essential for maintaining optimal levels.
How to Increase Phosphatidylserine?
There are three main avenues to elevate phosphatidylserine levels: dietary intake, lifestyle optimization, and supplementation. Each approach offers unique advantages.
Dietary Sources of Phosphatidylserine
Historically, humans consumed significant amounts of PS 100 phosphatidylserine from organ meats and cold-water fish. Modern Western diets are often deficient in these sources.
Animal-Based Sources
• Organ Meats:
Bovine brain (historically the richest source), liver, and kidneys contain high concentrations of phospholipids. However, due to concerns about prion diseases (e.g., BSE), bovine brain is no longer a recommended or commercially viable source.
• Fish:
Mackerel, herring, and tuna are rich sources. A typical serving of mackerel contains approximately 150–200 mg of PS 100 phosphatidylserine.
• Poultry and Eggs:
Chicken breast and eggs provide moderate amounts, with eggs offering the added benefit of phosphatidylcholine.
Plant-Based Sources
For vegetarians and vegans, plant-based sources are available, though typically in lower concentrations:
• Soy Lecithin:
Soy is the primary commercial source for PS extraction. Soy-derived PS is abundant in plant-based diets.
• White Beans:
These legumes contain measurable amounts of PS.
• Sunflower Lecithin:
While traditionally lower in PS 100 phosphatidylserine than soy, advancements in extraction have made sunflower lecithin a viable non-GMO alternative.

Dietary Limitations:
To achieve therapeutic levels of PS (e.g., 300–500 mg per day) solely through diet, one would need to consume unrealistic quantities of food. For instance, one would need to eat over 2 pounds of chicken breast or 50 eggs to reach a clinical dose. Therefore, while dietary sources support baseline levels, pure phosphatidylserine supplementation is often required for therapeutic effects.
Lifestyle Factors Affecting PS Levels
Before increasing intake, it is prudent to address factors that deplete existing PS levels. Chronic inflammation, oxidative stress, and poor lipid metabolism can accelerate the degradation of phospholipids in the brain.
• Manage Chronic Stress
Prolonged stress leads to the oxidation of cell membranes, depleting phospholipids like PS 100 phosphatidylserine. Incorporating stress-reduction techniques such as mindfulness, meditation, or regular low-intensity exercise helps preserve the structural integrity of neuronal membranes.
• Optimize Omega-3 Status
Natural Phosphatidylserine works synergistically with omega-3 fatty acids, particularly docosahexaenoic acid (DHA). DHA is incorporated into cell membranes, and PS facilitates its uptake. A diet deficient in omega-3s limits the functional efficacy of PS. Ensuring adequate intake of fish oil or algal oil maximizes the neuroprotective benefits of PS 100 phosphatidylserine.
• Reduce Alcohol Consumption
Chronic alcohol consumption disrupts phospholipid metabolism in the liver and brain. Alcoholics often exhibit significantly reduced PS levels, contributing to cognitive decline and "alcohol-related brain damage." Moderation or cessation of alcohol supports endogenous PS synthesis.
Supplementation with Phosphatidylserine
Given the limitations of diet and the impact of modern lifestyles, supplementation is the most reliable and effective method to increase phosphatidylserine levels.
Types of Phosphatidylserine Supplements

The source of PS significantly affects its purity, sustainability, and consumer preference:
• Bovine Cortex PS (BC-PS):
Historically derived from cow brains. While highly bioavailable, it is no longer commercially available due to safety concerns (BSE).
• Soy-Derived PS (S-PS):
The most common form in the supplement market. It is effective, well-researched, and cost-effective. However, some consumers prefer non-GMO or allergen-free options.
• Sunflower-Derived PS:
A newer alternative derived from sunflower lecithin. It is non-GMO, allergen-free (no soy), and suitable for vegetarians. Studies confirm it is equally as effective as soy-derived PS.
For manufacturers and formulators seeking high-quality raw materials, Guanjie Biotech is a phosphatidylserine supplier that specializes in both soy and sunflower-derived phosphatidylserine. Their products are characterized by high purity (typically 20% to 70% PS content) and rigorous quality control, ensuring that supplement manufacturers can deliver safe, effective products to consumers.
Recommended Dosages
Clinical studies have established specific dosage ranges depending on the desired outcome:
• General Cognitive Support: 100–200 mg per day for healthy adults.
• Age-Related Cognitive Decline: 300–500 mg per day, often divided into two doses (e.g., 200 mg in the morning and 200 mg in the afternoon).
• Athletic Performance & Cortisol Control: 400–800 mg per day, typically taken 30–60 minutes before exercise or stressful events.
• ADHD (Pediatric): 200–300 mg PS 100 phosphatidylserine per day, often combined with omega-3s.
It is important to note that phosphatidylserine is lipid-soluble and best absorbed when taken with food containing fats.
Synergistic Combinations
To maximize the efficacy of PS 100 phosphatidylserine supplementation, consider combining it with complementary nutrients:
• Omega-3 Fatty Acids (DHA/EPA):
As mentioned, PS aids in the membrane incorporation of DHA.
• Phosphatidylcholine (PC):
Often found in lecithin, PC supports liver health and cell membrane integrity.
• Ginkgo Biloba:
This herb is often combined with PS to enhance cerebral blood flow and cognitive outcomes.
Who Should Supplement Phosphatidylserine?
While PS is beneficial for a broad population, specific groups derive particular advantages:
• Aging Adults
As PS synthesis declines with age, supplementation can help mitigate age-related cognitive decline, supporting memory retention and mental clarity.
• High-Performance Athletes
Athletes undergoing intense training schedules benefit from PS's ability to modulate cortisol, reduce muscle soreness, and support mental focus during competition.
• Students and Professionals
For individuals facing high-stakes exams or demanding work environments, PS 100 phosphatidylserine can improve concentration, reduce test anxiety, and support memory consolidation.
• Individuals with Mood Disorders
Those suffering from mild to moderate depression or anxiety may benefit from PS, particularly if their condition is linked to chronic stress and elevated cortisol.
• Individuals with ADHD
Children and adults with ADHD often exhibit phospholipid deficiencies. PS 100 phosphatidylserine can serve as a valuable adjunct to standard treatments, improving attention and reducing hyperactivity.
Conclusion
Increasing PS 100 phosphatidylserine is a scientifically validated strategy for enhancing cognitive function, managing stress, and supporting athletic performance. While dietary sources like fish, eggs, and soy lecithin provide a baseline, modern diets and lifestyle stressors often necessitate supplementation to achieve therapeutic levels.
When choosing a supplement, the quality of the source material is paramount. Whether opting for soy-derived or sunflower-derived PS, consumers and manufacturers should prioritize purity, transparency, and rigorous testing.
